I completed the mission but didn't get my summoner icon reward :/

As I get on league to play, I see this new mission and I just say sure I'll complete the mission because it gave a cool summoner icon as the reward and i've seen posts about this new game mode coming out too, but when I win one match made pvp game (which is what you have to do to complete the mission and get your reward) I went home and immediately went to equip the new icon but I guess it was never added to my inventory for some reason. So I went back to make sure I completed the mission and the mission was in my view completed list, so I did complete it but I just didn't get my reward, I don't know if this is a bug or what but I'm hoping I get someone from riot or something to fix this because without the icon it makes it impossible to complete the other missions. (You need to have the new icon equipped and complete whatever assignment they give you to complete the mission). Sorry this post was long but I hope someone can fix this :P
